Problems solved by technology

However, both of them are far from the requirements of inter-satellite communication: it is difficult to generate high-power terahertz signals based on the laser principle (the infrared laser source power of NASA in the United States is only 0.5 watts); Although the power of the millimeter wave source can be made very high, due to the limitation of size and power consumption, it is impossible to realize the satellite

Abstract

The invention discloses a method for realizing a high-power THz source based on space beamforming. According to the method, a plurality of THz array elements are arranged to form an antenna array, wherein each THz array element is composed of a THz active device and a THz on-chip passive antenna connected with the THz active device, the THz active device feeds a THz signal into the passive antenna and then the passive antenna radiates out THz waves; high-power THz wave output can be formed through adjusting the emission intensity and phase of different THz array elements in the antenna array to carry out beamforming and energy concentration. A phased-array antenna array is used for adjusting the directivity of a wave beam to realize alignment of the emitted beam and the receiving direction; the beamforming method is used to realize high gain.

Description

technical field [0001] The invention relates to a novel terahertz signal source based on semiconductor technology for inter-satellite communication. Background technique [0002] Terahertz technology has broad application prospects in military applications and wireless communications, especially in space communications that require high bandwidth and security. Terahertz (THz) frequency band is higher than millimeter wave but lower than long-wave infrared, and its frequency range is between 0.3THz and 30THz (wavelength 1mm~10μm). Compared with millimeter wave communication, terahertz communication has the characteristics of large bandwidth, small antenna, good directionality, high security, anti-electromagnetic interference and small scattering; compared with free space laser communication, terahertz has good frequency selection characteristics, Anti-background noise, easy alignment, multiple modulation modes, etc., are especially suitable for inter-satellite link communicat...
